UPF 50+ sun protection

UPF protection is inherent in the fabric and will not diminish due to laundering

The Foundation's Seal of Recommendation is granted to sun protection products that have been reviewed by and meet the stringent criteria of an independent Photobiology Committee.

One of the first programs offered by the Foundation, it quickly gained acceptance from consumers for setting the standard for effective sun protection with sunscreen products, sunglasses, specially treated auto and residential window film, umbrellas, clothing and laundry products that wash UV protection into clothing.

To earn the Seal of Recommendation, a manufacturer must provide scientific data showing that its product sufficiently and safely “aids in the prevention of sun-induced damage to the skin.” The data are reviewed by a volunteer committee of photobiologists – experts in the study of the interaction between ultraviolet radiation and the skin.

Products using the COR3™ Technology fabric finish have a UPF rating of 30 or greater, properties to minimize odor and outstanding wicking performance for important moisture management. The anti-odor finish helps control odors caused by a wide range of microorganisms (mold, mildew, algae, yeast) is compatible with virtually all fabrics. All of our performance cotton clothing utilizing COR3™ also feature COR3™ EZ. The "EZ" means easy care and indicates that garments featuring this treatment will travel well and resist wrinkles.
